$right¶
Usage: $right(text,number)
Category: text
Description:
Returns the last number
characters from text
. If number
is less than 1, then the
value used is the number of characters in text
plus number
(e.g.: $right(abcd,0)
is the same as $right(abcd,4)
). If number
is missing or a negative number greater
than the number of characters in text
, the function will return an empty string.
Example:
The following statements will return the values indicated:
$right(abcd,2) ==> "cd"
$right(abcd,0) ==> "cd"
$right(abcd,-1) ==> "bcd"
$right(abcd,) ==> ""
$right(abcd,-5) ==> ""
